Yeah, you are in a tough spot. Algae and Floc. We can't deal with the algae, cause we need to kill it and remove it to regain visibility, which requires filtration. Dealing with the FLOC requires us to get it out, but we can't see it to vacuum efficiently.
@mknauss and
@JoyfulNoise, you guys agree on getting as much of the FLOC out first, then deal with the algae, even if we need to clean the grids containing some errant FLOC?
It may be that we will end up with some FLOC in the filter later, and will deal with that if it comes. Sounds like you are committed and methodical. That REALLY helps.
